Authorities do not suspect criminal activity in the death of a Winneconne man who's body was discovered in a burned car.

The body of Jeff MacDonald, 44, was found in a burned vehicle early Monday morning on County Trunk S and Leach Road in the town of Oshkosh.

Detectives from the Winnebago County Sheriff's Office continue to investigate. They have received some information about MacDonald's whereabouts the night before authorities were called to the burning vehicle at 3:50 a.m. Monday. At this time, they have no reason to believe any criminal activity resulted in MacDonald's death, Winnebago Sheriff's Capt. David Mack said.

Mack said investigators are waiting for autopsy and toxicology results.

Anyone who had contact with MacDonald between Friday and the early morning hours of Monday is asked to contact Detective Ron Timm, (920) 236-7369.
